Firebird upgrade

I inherited a situation with 2 Canon imagePRESS C1+ with server Q2. Due to vulnerabilities associated with the Operating System (Windows XPe) and the version of Firebird running on the servers, both are now disconnected from the network. The support company was contacted and they stated that there is no upgrade path for multifunction devices. If the server OS is upgraded to Windows 7 Enterprise, is there a way to upgrade the version of Firebird to 2.0.1 or later and still be able to use the Fiery software installed? The servers are running Fiery for iPR Server Q v 2.0 and Fiery User Software 3.7.0.15.
